'El REEL', Eli/Af in such o structure.

The main objects of my in'venion :ire:

First, to provide an improved silo of the.

lock or stave type in which the blocks :ne eectively inierlociied. Second, to provide in a silo an improved strucure providing e series of uniform door openings.

Further objecs, and objects reieting structural details, will denitely appear from the detailed description to follow.

I accomplish he objects of my inventief. by the devices ansi means describeci in (che following specification.

The invention is clearly le-inea?. pointed out in the claims.

A structure which is o prcicrred emlooiment of my invention is clearly illustrzied in the accompanying dre ing, forming .fr part of this specification, in which:

Figure is a front elevation of e silo structure embodying the` features oi my invention. Fig. H is an enlarged detail vertical section on :i line corresponding to line 2 2 of Fig. I. Fig. IH is :L front elevation of one of the door casing blocks. iV is a front elevation of one of one wall blocks. Fig. V is o detail horizont-ei' seciion on e, line corresponding to iine'5-5 of' Fig. "i, showing the forni of the abutting edges of the blocks.

n the drawing similar reference characters refer to similar paris throughout ille several views, and she secionei views are taken looking in the direction of the litie arrows at the ends oi the section Eines..

2. A cylindrical wall structure of the cla'ss described, comprising wall blocks having tapered centrally disposed interlock projections at their ends, the bases of the projections being spaced from the edges of the blocks providing shoulders at each side thereof, said blocks being laid in courses with the interlock projections of adjacent courses interlocking, the ends of the interlock projections abutting the shoulders of abutting pairs of adjacent courses, Jframelike door casing blocks laid in alternate courses of said wall, said casing blocks having door openings therein, the spaces between said casing blocks also constituting door openings,- tlie ends of said casing blocks being shouldered to coact with the ends of the abutting blocks of adjacent courses, and encircling hoops disposed across the interlock projections of said courses of blocks and the ends of said casing blocks.

In witness whereof, I have hereunto set my hand and seal in the presence of two witnesses.
